That's the purpose he ended up with but I highly doubt that was the intended purpose and it still makes the character incredibly dumb as all he was in TPM was low-brow childish comic relief. Hate all you want on C3P0 but we didn't get long, extended, scenes of him just being a complete comic-relief doofus stepping in poop.
